blob: 1f46c1511b2dcb3715fe6be49bbf2bec12b71418 (plain)

The po plugin needs to be updated to match the urlto sub API and signature changes. Else a wiki with the po plugin enabled cannot be refreshed / rebuilt because of (correct) Perl errors.

My po branch contains a fix. --[[intrigeri]]

The commit looks sane to me, for what it's worth. Joey, please consider merging? --[[smcv]]

Merged. --[[Joey]]

Also, I fear the lack of any useful $from parameter might break some l10n'd link niceness when using po_link_to = current but I have not investigated this yet. --[[intrigeri]]

If urlto is called without a second parameter, it means we need a URL valid from either the CGI URL or any page in the wiki, (so we'd previously have set the third parameter true), but we don't necessarily need an absolute URL - so return what you'd have returned if asked for an absolute URL, but looking like /bugs/ rather than http://ikiwiki.info/bugs/ if possible.

It looks as though beautify_urlpath under po_link_to = current, and 3-argument urlto, aren't tested by t/po.t - perhaps you could add some test cases there? To test 3-argument urlto you'd need to add $config{baseurl} = "http://example.com" or something. --[[smcv]]

I'm leaving this bug report open until this can be checked. --[[Joey]]

My ready/urlto branch improves the test coverage. The bugfix from that branch fixes most of po too, but leaves behind some perhaps less-than-ideal behaviour: links where the current language is unknown, with po_link_to = current, always go to the master language, whereas perhaps it'd be better to go to the negotiated language in this case? --[[smcv]]
